These pages are about our search of "a protocol for the incremental exchange of metadata about geographic resources between systems" which is open, lean and mean. Proposals like OGC's CSW 2.0 do not fulfill these requirements. Profiled specifications like WFS or OAI-PMH (see below) are currently on our short list.

These are experimental pages originated from OSGeodata Mailing List on OSGeo.org.

Let's finally unleash geographic information through open access and dissemination of geographic data and (metadata) search appliances!

Managing metadata well is the key to making a repository of open geographic data really useful and re-usable. Creating metadata can be a dull chore. Part of the problem is over-focus on production, rather than consumption; on standards, rather than on usage. The Geodata Committee at OSGeo has been working on a "simplest useful thing" approach to geographic metadata.... (Citation from Jo Walsh)

Towards a new geographic catalog protocol...

After having agreed on a better protocol there is also a need for a better name, like 'Geographic Metadata Harvesting Protocol'.

For general protocol requirements read OSGeodataMetadataProtocol. We tend to propose a harvesting approach which means, that in a first step XML files are pulished and in a second step OAI-PMH could be utilized.

For proposals around the metadata information model requirements see OSGeodataMetadataModel.

Need for a metadata information model

We definitively need a metadata information model. See OSGeodataMetadataModel for further discussion.
